"Lark Rise to Candleford" surprised me by quoting "Waste Not, Want Not" which used to be frequently played on a local radio show.

James Baldwin's novels and short stories sometimes quoted blues songs, spirituals, etc., and even took their titles from songs, e.g. "Go Tell It on the Mountain," "If Beale Street Could Talk" (The latter song doesn't seem to be in the DT, but I know the Red Clay Ramblers recorded it.)

"If Beale Street could talk, if Beale Street could talk,
Some married men would have to take their bed up and walk."

Thomas Hardy wrote a hilarious short story called "Absent-Mindedness in a Parish Choir."
